2-Bromo-1,3-dimethyl-5-(pentyloxy)benzene CAS 91881-79-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1,3-dimethyl-5-(pentyloxy)benzene.

2-Bromo-1,3-dimethyl-5-(pentyloxy)benzene (CAS 91881-79-7) is a high-purity analytical reference standard with the molecular formula C13H19BrO and a molecular weight of 271.19 g/mol.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-1,3-dimethyl-5-(pentyloxy)benzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 271.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
